Abstract (en)
[origin: EP1052124A2] A vehicular refrigerating cycle with a by-pass line 55 is provided, whereby even in an environment of extremely low temperature with the refrigerating cycle left at rest after being operated in cooling mode, refrigerant accumulated in a condenser can be driven out of said condenser 52 to provide subsequent heating functions by an evaporator 54 in a prescribed manner. Capacity control means 20 can be set such that the capacity of a compressor 10 only is allowed to start to decrease from a maximum capacity when a compressor suction pressure Ps has dropped to a value of 2 atmospheres (absolute pressure) or less in a state in which refrigerant flows through condenser 52 without passing through by-pass line 55. <IMAGE>
